I think you should update your addon, it is getting a few bugs with newer Firefox, thanks.

"Failed to save" .. anytime I tried downloading anything.

的确多线程，可是下载也慢，合并也慢……

For some weeks now the extension stopped working for me.
It will only use 1 thread, despite being set to use more, and it will always stop with an error before completing the download.

The only thing i would add to this, is being able to whitelist or blacklist a site from using the extension. There will be sites that i will never going to use it, and there are others that i will always use it, so i don't have to see a prompt asking me what to do on those cases.

La meilleur extension de téléchargement pour Firefox !

thank you very much for your time and effort.
works great for me.

this is the most useful plugin for Firefox you can find

有时候会调用到浏览器自带的下载工具,怎么解决,不能完全替代

浏览器在副屏显示情况下，无法正常显示下载提示

Расширение отличное.Добавьте,пожалуйста,функцию загрузки торрентов.

it doesn't capture every download.
